[Eug-lug] Shell scripts to export environment variables?

[Rob Hudson]

I've got some Python scripts that rely on shell environment variables
for certain things.  I wrote a simple script that did an export but it
didn't take, and I'm guessing that the shell script gets its own
environment, that when the script terminates goes away.

Is there a way to write a shell script that can export an environment
variable to the calling shell?

I know I can set environment variables in Python, but I want to keep
things modular so I can re-use the Python script and do things based
on different environment settings.

Thanks,
Rob
